Factoring Trinomials using Slide­DivideIf there is a trinomial that after checking 

for GCF still has a number in front of the x2, factor using the slide­divide method.

3x2 ­ 2x ­ 5

S Slide

1. Multiply the number in front of the x2 to the product and re­write your trinomial.

3x2 ­ 2x ­ 5

F Factor

2. Factor the trinomial using product­sum.

3x2 ­ 2x ­ 5

D Divide

3. Divide both numbers in factored form by the  number that you slid (# in front of the x2).

3x2 ­ 2x ­ 5

R Reduce

4. Reduce the fraction, if possible. If not, leave it  alone until the next step.

S Slide

5. Take the denominator that cannot be reduced  and slide it in front of the x in the same  

    parenthesis.
